Jhorse is a solar power system supplier and manufacturer that provides various kinds of solar power products.
1. System Composition
A residential solar power system mainly consists of the following key components:
(1) Solar Panels: The core of the system, responsible for converting solar energy into direct current (DC) electricity, typically accounting for 40%-50% of the total system cost.
(2) Inverter: Converts DC to alternating current (AC) for use by household appliances, accounting for approximately 15%-20% of the cost.
(3) Controller: Regulates the charging and discharging process of the solar panels, preventing overcharging and over-discharging, and protecting the system's safe operation.
(4) Battery: Stores electrical energy for use on cloudy days or at night, accounting for approximately 20%-50% of the cost.
(5) Brackets, cables, and other auxiliary materials: Used for installing and connecting various components, accounting for 5%-15% of the total cost.
2. System Selection
(1) Power and Capacity Design
A: Assess Electricity Demand: Calculate the daily electricity consumption of the household (kWh), such as the total power consumption of lighting, television, refrigerator, etc.
B: Determine Power Generation Demand: Calculate the total power required for solar panels based on electricity consumption and local sunshine conditions.
C: Consider Energy Storage Capacity: To cope with cloudy and rainy days, 2-3 days of energy storage is generally required.
(2) Key Equipment Selection
A: Solar Panel Type: Monocrystalline silicon solar panels are highly efficient and have a long lifespan, suitable for household use; polycrystalline silicon solar panels are less expensive but slightly less efficient.
B: Inverter Selection: Select a matching single-phase or three-phase inverter based on the system power and load type.
C: Controller Matching: Voltage and current specifications must be compatible with the solar panels and batteries.
(3) Installation Conditions
A: Roof Type and Orientation: Sloping roofs are suitable for installation, with a south-facing orientation being optimal to ensure unobstructed views.
B: Roof load-bearing capacity: The roof structure needs to be assessed to ensure it can withstand the weight of the solar panels and supports.
3. Costs and Return on Investment
(1) Cost Structure
A: Equipment Costs: Hardware costs such as solar panels, inverters, controllers, and batteries.
B: Installation Costs: Including construction and commissioning.
C: Other Costs: Design fees, grid connection application fees, transportation fees, etc.
(2) Return on Investment
A: Power Generation Revenue: Estimating annual power generation and electricity cost savings based on local sunshine and electricity prices.
B: Subsidies and Policies: Some regions offer initial installation subsidies or electricity price subsidies, which can accelerate the payback period.
C: Payback Period: Generally 5-8 years; system lifespan can reach over 25 years.
4. Installation and Maintenance
A: Professional Installation: It is recommended to have the installation performed by a qualified installer to ensure safety and quality.
B: Routine Maintenance: Regularly clean the solar panels and check the wiring and equipment operation status.
C: Troubleshooting: Choose a brand with good after-sales service to ensure timely repairs.
5. Suitability Assessment
A: Suitable for installation: Families with good roof conditions, high electricity consumption, and long-term residence plans.
B: Not suitable for installation: Areas with aging roofs, severe obstructions, or no power grid connection.
